Mac Mini Led blinks but wont boot, no chime.

crwdns2934249:0crwdne2934249:0:

Hello guys, I´ve received an mac mini late 2014 A1347 for repair and it wont turn on.

Specs are Dual Core i5 2,5Ghz, 8Gb RAM, 1Tb HD.

After I openned it up, I see that the cooler tries to spin but then it stops, checked the power supply from the machine and its giving 12v as it should be, on power supply after I press the power button it goes to 0,4A then zero, then 0,7A then zero again, and it repeats over and over again...

HD is Ok, I can boot from it using another mac, Power Supply is Ok, buttons, flats, I´ve already rehoted the RAMs chips that are soldered to the board just to make shure (theres no beep indicating RAM problem...)

I dont know what else can it be, anyone can help me with an scheme or an more advanced tech tip?

Thanks!
